Research indicates that single checking of medications is as safe as double checking; however, many nurses are averse to independently checking medications. To assist with the introduction and use of single checking, a measure of nurses' attitudes, the thirteen‐item S ingle C hecking A dministration of M edications S cale ( SCAMS ) was developed. We examined the psychometric properties of the SCAMS . Secondary analyses were conducted on data collected from 503 nurses across a large A ustralian health‐care service. Analyses using exploratory and confirmatory factor analyses supported by structural equation modelling resulted in a valid twelve‐item SCAMS containing two reliable subscales, the nine‐item Attitudes towards single checking and three‐item Advantages of single checking subscales. The SCAMS is recommended as a valid and reliable measure for monitoring nurses' attitudes to single checking prior to introducing single checking medications and after its implementation.
